I am running Xubuntu 13.10 i386 with the python (2.7) and python3 (3.3) packages installed. I have downloaded and compiled the source code for Python 3.4 but the binary file is named python. How can I install it as python34? Do I change the name of the binary file and do sudo make install?

Since pip does not seem to be included by default, if you want it, just run python3.4 -m ensurepip --upgrade, then you can use pip in this way: python3.4 -m pip install ModuleName.

For example, I do not have any Python installations on my system and I want to install 3 versions: 2.7, 3.3 and 3.4. I want to make 2.7 the primary installation (as python) and all the others as secondary (as python3.3 and python3.4) installations. I would install the primary with:

sudo make install

and install both the other versions with:

sudo make altinstall

The produced programs would be python (2.7), python3.3 (3.3) and python3.4 (3.4)
